If there are N shell passes in a shell and tube HE, then which one of the following relation is correct foe the pressure drop a shell side?

\((\frac{FL}{D}+N)\frac{v^2ρ}{2}\)

\((\frac{FL}{D}+4×N)\frac{v^2ρ}{2}\)

\((\frac{FL}{D}+N)\frac{v^2ρ}{2}\)

\((\frac{4FL}{D}+N)\frac{v^2ρ}{2}\)

\((\frac{4FL}{D}+4×N)\frac{v^2ρ}{2}\)

If there are N shell passes in a shell and tube HE, then which one of
